Improvement in coal-sifters



UNITED STATES PATENT OEEIcE.

IMPROVEMENT IN COAL-SIFTERS.

Specification forming part of Letters Patent No. 53,254, dated March20,1866.

specification, is a description ot my invention sufficient to enablethose skilled in the art to practice it.

In the various kinds ot' coal-sitters in common use, in which thesitting-pan is agitated over a barrel or ashes-box by means ot a handleor crank, the high cost ot the sitters prevents their general adoption,and a cheap anda etfective sitter so constructed that it can be appliedto or supported wit-hin the top of a barrel, with a provision foragitation ot the same, is a desideratum.

By my invention I obtain an article ot' very simple construction, easilyoperated, costing but very little more than the common round handsifter,applicable to any barrel or ashesreceptacle, and more effectivethan-most of the complicated and expensive sitters now in use. E

The drawings represent a sitter embodying the invention, Figure 1showing a plan ot the sitter. and Fig. 2 a section of the same appliedto a barrel.

a denotes the body ot the sitter; b b, journal-pins by which the same issupported Within the ashes barrel or receptacle c. These journals turnin bearings or slots, and extend out beyond the opposite sides ot thebarrel, and have applied to their outer ends a rodorhandle, d, whichextends upfrom the journals and diametrically over the sitterin line otthe journals,

as seenin the drawings. The sitter box or body a is made ot a diameterconsiderably less than the diameter ot that part of the barrel where thesitter is suspended, and by means ot the journals itis suspended in thebody ot'thebarrel, so that When charged it can be rocked to and tro indirections perpendicular to the line of the journals by application otthe hand or hands to the cross-rod d, the rocking motion carrying theopposite sides ot the sitter alternately against the oppositesides otthe barrel, and the agitation and jarring ot the coal and ashesconsequent upon such movements quickly separating the ashes from thecoal. The dust may be prevented from rising during the shaking processby placing a cover, e, upon the barrel.

The invention consists, therefore, in the application to journal-pins bywhich the sitter is suspended in the ashes-receptacle ot a rod or handleextending upward from and diametrically over the sitter or box, so thatthe sitter may be rocked to and tro within the barrel, as abovedescribed.

It Will be obvious that this construction is inexpensive, that thesitter so hung can be very easily operated, and that no arrangement canbe more simple and effective in-separating ashes from coal.

I claim as my improvement in barrel coalsittersl. So making andarranging the sieve with long journals that it may be traverseddiametricallyin the barrel or rocked, as preferred, or alternatelyrocked and traversed.

2. Making the journals and handle ot' a bent Vrod ot metal,substantially as described.

In witness whereof I have hereunto set my hand this 10th day ot'October, A. D. 1875.
